At Central Beach in Balneário Camboriú, retaining walls progress in sections while the southern shore receives restinga and underground cabling as part of a revitalization plan that extends to 2027.
At Central Beach in Balneário Camboriú, retaining walls are being built in stages on the southern shore to secure the sand from the widening, protect Avenida Atlântica, and provide a foundation for the new boardwalk, bike lane, and communal areas. The construction fronts are spreading across successive sections, involving excavation, rubble at the base, and concreting, discreetly reshaping the beach’s structure while the daily life of residents and tourists continues alongside the barriers.
At the same time, planned restinga and underground cabling are becoming part of the revitalization package, replacing exposed wiring with buried ducts and preparing a cleaner environment for those walking along the southern shore. With a schedule indicating deliveries starting only in 2027 for some segments, the transformation is advancing at the typical pace of public works, but with the promise of turning this stretch of Central Beach in Balneário Camboriú into a new tourist postcard once everything is complete.
Retaining Walls Redesign the Southern Shore of Balneário Camboriú
The video shows the progress of the work fronts at Central Beach, starting from Barra Sul. Right at the entrance to the Armani Casa and Blue View areas, it is already possible to see a new phase beginning, with retaining walls taking shape on the sandy strip.

A trick with joint compound transforms a Styrofoam ceiling into a plaster-like ceiling: leveled panels, wires and mesh at the joints, sand, paint, and change the environment while spending little today.
This stretch between Rua 4700, Blue View, Armani Casa, and Faros marks the beginning of another phase of revitalization. First, the teams set up the construction site, excavate, prepare the base with rubble, and begin to raise the underground retaining walls, which will later be covered and integrated into the landscaping.
According to reports, the plan for the southern shore is broken down into successive stages. There is a first part already completed, a second in an advanced stage near Sena, and a third currently being executed in front of new buildings, to be followed by a fourth section up to Molhe da Barra Sul. The forecast is that this sequence of retaining walls will consolidate the entire structural base of the widened beach in this sector before work advances to the north.
How Retaining Walls Work at the Widened Beach
As you approach the construction sites, the video captures the open trench on the sandy strip and the base material. At the bottom, the rubble stones that support the retaining walls can be seen, forming a robust foundation to withstand the tide’s force and the weight of the fill.
After the rubble is laid and compacted, the retaining walls are executed from the bottom up, with reinforcements and concrete.
Next, the section is backfilled, concealing the structure and allowing the construction of the boardwalk, walking path, and bike lane over this buried “wall.”
Another important point shown is the lowering of the groundwater level. Pumps connected to blue and red hoses are continually working to remove water from inside the excavation.
Since the teams are operating below the groundwater level, the lowering is essential for the retaining walls to be concreted safely and with quality.
Restinga and Sand Retention as Natural Protection
In addition to the concrete structure of the retaining walls, the revitalization plans for a layer of natural protection. In the video, the narrator reminds us that the entire beach is to receive restinga along the widened strip, precisely to hold the sand that currently still blows away with the wind.
Without vegetation, the newly placed sand tends to be carried to the avenue and the bike lane, requiring constant maintenance.
With the restinga planted over and in front of the retaining walls, the whole structure begins to function as a double barrier, combining engineering and nature to stabilize the new shoreline.
This combination of rigid solution and vegetation is crucial for the southern shore of Balneário Camboriú to maintain a wide and usable beach over the years, reducing the impact of storm surges and wind on urban infrastructure.
Underground Cabling and Buried Infrastructure Beneath the New Shoreline
In one of the already advanced sections, near Sena, the retaining walls appear finished and backfilled, while teams work on the buried infrastructure. This area is focused on pipes and ducts for electrical, hydraulic, irrigation, data, and public lighting services.
The video highlights the black boxes and tubes that will serve for the underground cabling, allowing energy and other services to reach the posts and light points along the shore without visible wiring.
According to the mentioned information, the city hall intends to remove the electrical wiring from the left side of Avenida Atlântica in a later phase, after the beach and sidewalk area next to the sea are completed.
Thus, the construction sequence is clear: first, retaining walls and drainage; then, buried infrastructure and underground cabling; followed by the boardwalk, walking path, bike lane, and landscaping, with the restinga and other visual elements that will compose the new scenery.
Phased Timeline Until 2027 and Future Progress for the Northern Stretch
In the area in front of Sena Tower, the construction sign gives clues about the pace of the schedule. The start of execution is indicated, and the projected timeline suggests a completion only in 2027, which the narrator reinforces by stating that the delivery is not expected to happen this year, but in mid-2027 for this segment of retaining walls and the boardwalk.
For the southern stretch as a whole, the forecast is that important parts will be delivered sooner, while others will only close the cycle throughout 2027.
Meanwhile, the city hall is working on a new bid specifically for the northern stretch of Central Beach, with the expectation that construction will begin after the consolidated progress of the southern shore.
This means that the retaining walls currently appearing in front of Blue View, Armani Casa, Faros, and Sena are only part of a larger plan.
As each phase is completed, Central Beach will gain continuous stretches of requalified boardwalk, organized bike lane, and a cleaner visual environment, without so many overhead cables.
Southern Shore on the Way to a New Tourist Postcard
Even with the work proceeding at a pace that the narrator considers “rather slow,” the transformation is already visible. Where the retaining walls are finished, the backfilling is complete, and the flooring is stored awaiting installation, the future communal area between beach, boardwalk, and bike lane is already taking shape.
As restinga, landscaping, and underground cabling are finalized, the southern shore of Central Beach in Balneário Camboriú is expected to solidify as a new tourist postcard, combining tall buildings, wide sandy strip, and a modernized waterfront.
For those who live in or visit the city, the path to 2027 will involve dealing with barriers, machinery, and constant changes in the landscape.
In the end, the retaining walls are the silent foundation of this change, securing the sand, tide, and infrastructure, so that everything visible on the surface can function safely and last longer.
Images and information were obtained from a video recording from the channel Fala JC.
And you, do you think that the pace of works and the use of retaining walls at Central Beach in Balneário Camboriú will be worth the wait when the southern shore is fully ready?
